JAR-TRIMMING MACHINE.

Appiicaiion'fiied Marcil 4, i924. serial Noueesm.

y This invention relates to machines for applyingto. glass. fruit jars and the like the trimmings or metallic portionsby means of which the top is secured in place on'thel i jar. The invention relates especially, although not exclusively, to jar trimming machines otthe typeshown anddescribed in niyprior Letters .Patent No. 1,456,276, May 1923, and has 'for its general objects to improve and siiiiplily `machines of this charable operation, whereby the4 possibility vot' defective work is reduced to a minimum and `the capacity o'tthe machine increased.

The more particular object-s ot Athe inventiointogctlier withiiieiins u'lierebyihe same iiiayhe carried into elfect, will best be imderstood from theiollowing description ot a preferred embodiment thereof ilhistrated in the accompanying drawings. lit will be un derstood, however, that the particular constructionA described and shown has been.V

:chosen for illustrative purposes merely, and that the invention, as deiined by the claims hereunto appended, may he otherwise praetisedwithout departure froiiithe spirit and .scope thereof.

Figs. -15 and '16 are detail 'views illustrating the positioning` oi the ends oit the lwires. Referring to Figs. 8 and 9, at ifi is .shown the arto which the trimming is to be applied,

theiieck being shown at i and the coverat The trimming herein shown consists of a tie `wire C and tivo hook-shaped clamps D,

The mechanism l'orliend'iiig the tie wire C about the neck of the j ai-A connL rises a bender i 30 and a pair ot wipers 3l. which, as herein shown, are carried'atthenp per ends oit' elongated levers 3Q and pivoted at their-lower ends to brackets and carried by the base 2l and extending through slots and 37 tofthe table Q0. Thelever 32, which carries the bender S0, as operated by meansot a spring 38 secured atone end to said lever `and atrthe other to the table 20, while the levers 33, 'which carry the 'wipers Share operated by springs 39 each secured atone end to its Arespective lever-33 and at its opposite end to'said table, the syn-ing 38 'tending normally to-draiv `the bender BOtoward the jar. and the springs 39 tending normally to draw the wipers 3l toward one another. The n'iouenients ot the levers 32 and 33, under the iii'thieiice ofthe springs 38 and 39, are controlled by a cam bar 10 having a `wedge portion 4l interposed between the levers 33 and an end Vportions-2 constituting a. pusher which engages the lever 32. The cani bar L i(linaybe moved longitudinally by any suitable mechanism, saidmechanism, as herein shown, comprisnga piston 43 secured tosaid cam bar and operating' in a fluid pressure cylinder i4 supported by a bracket 45 beneath the table 20 and adapted to receive siiik pressure llnid through pipes 46 under the control of anysuitahle valve mechanism, not shown.

The bender 30 comprises a pair of arms disposed respectively at, opposite sides ot the centre ol the jar A and termed suhstantiallv to tit the neck (t when moved into engagement therewith. The wipers 3l. which are located at the opposite side ol the Iiai' from the hend'er 30. are similarly termed to conform with the shape olf said neck at their points of engagement therewith. 'lhe liender 30 and wipers 3l are each formed at their ends with notches to engage the wire C.

ln operation, the operator places the tie wire ol' a trimming in the notches in the ends ot' the arms of the liender 30, as shown in Fig. 6, and holds the saine in said notches` unl-il lluid pressure is admitted to the cyliir der Lll in such ay inanne as to move the cani har 40 rearwardly7 or toward the right in Fig. 1. The lirst step of such movement is to perinit the lever 32 to more under the iiitluence ot the spring 3S, the levers 33 lieiiig still held apart. by llat, portions 4T on the wedge 'll. Moveiiient ol" the lever Si. causes the tie wire C to he partially lient about the neck ot' the jar, as shown in Fig. 1t). There after, continued movement of the cani liar l() permits the springs 3S) to draw the levers 33 and wipers 3l toward one another, said wipers7 hy engagement with the wire C, completing the bending so as to cause the ends of said wire to be crossed. as shown in Fig. ll. ready 'lor the action ol' the twister hereinafter described. llloveiiient ot' the cani liar 4() in the opposite direction serves to separate the wipers and retract the liender 3U, thereby restoring the parts to their original position.

Mounted on a bracket 50 on the upper side ol the table 2O is a traine 51 in which is mounted, for rotar)1 and axial movements a horizontal shalt 52 carrying at its end a twister for twisting together the crossed ends ol the wire C. As shown mostl clearly in Figs. 3 and el, the twister comprises a head 53 secured, as h v a setscrew 5l, to the `end of the shaft 52 and having lixed thereto a pair of spaced parallel flattening or depressing lingers or iiienihers 55 syn'nnetrically disposed with respect to the axis ol' said sha'lt. Guided on the lingers lior movement in the direction ol the axis of the twister is a slide 5G formed with a pair ol' spaced parallel lips 5T separated hy a V- shaped nose 58 adapted to enter between the crossed ends of the tie wire, which ends are received between said lips. Iiiterposed lie-- tween the head 53 and slide 5G is a spring 59 tending' normally to hold said parts sep arated while permitting the slide to yield in the direction of the axis of the twister. The outward movement ot' the slide 56 under the intluence of the spring 5,9 is limited hy studs (30 on the lingers which engage notches in plates (il secured to the slide.

Secured to the shalt 52 within the frame .'il is a cylindrial cani menihcr (S2 havingr a helical groote (S23. Guided on the frame 5l. l'or reciprocatori,7 motion in a direction parallel to the a.\:is of the shaft. and twister.` is :i slide ('i-l having: :i central opening to rcceive the cani nieinlier G2. 'l`he slide (il is reciprocaled iii the vl'rame 5l h v meansl ol" a liil'urcaled lever (35 comprisingr a pair ol' arms .secured to a rock shalt (it journalled in the lnacli'et 15, the outer ends ol' said arms heiner slotted to receive studs (3T and (.371 projecting lroni the slide (54. 'l`he stud (iT is extended into the openiiiit iii the slide to en' gage the groove (33 in the cani ineinher (52, as shown in Fig. The outer end ot the cam nieiiiliier (i2 is l'ornied willi a longitudinal hore to receive the end of a guide incur her (S8 havingr a 'feather li.) which is received in an interior longitudinal groove in said cani inemher. thereby forming a splincd connection lietweeii said parts adapted to hold the shalt .T12 against rotation while permitting axial n'iovement thereof'.

In operation. after the lie wire C has heen lient around the noch of the jar hy the liender il() and wipers 3l, as ahove explained and as shown iii Fig. ll, the arms (la are rocked to move the slide (i4 'l'orward or to ward the left in Fig. l.

Said lever is returned to normal position, when the piston rod is retracted, by means of a spring 82 connected 'atl one endtothe lever 65 `and at its opposite end to i the tableA "20.
